  1. Teach data science and they will come Joint Statistical Meetings

    2015, Seattle, WA Jennifer (Jenny) Bryan Dept. of Statistics & Michael Smith Laboratories, UBC [email protected] @JennyBryan http://stat545-ubc.github.io @STAT545 http://www.stat.ubc.ca/~jenny/ @jennybc
  2. The Big Data Brain Drain: Why Science is in Trouble

    http://jakevdp.github.io/blog/2013/10/26/big-data-brain-drain/ in a wide array of academic fields, the ability to effectively process data is superseding other more classical modes of research
  3. Exploratory Data Analysis grad course at UBC since 2008 (at

    least) Statistics for High Dimensional Biology grad course at UBC since 2001 w/ R. Gottardo, P. Pavlidis, G. Cohen-Freue, S. Mostafavi Software Carpentry, Data Carpentry, Reproducible Science since 2012
  4. 250 = cumulative enrollment 2008 - 2015 54 = #

    distinct programs sending students 25 = # programs with 2+ students
  5. Key Aspects of Program • Curriculum designed completely from scratch

    • 9 courses (free or $49 signature track) • 1 capstone project course w/ industry partnership • Total signature track cost (modular): $490 • Each course is four weeks • Every course runs every month • Quizzes, in video quizzes, programming assignments and peer assessment projects • All content open source with permissive license on GitHub Johns Hopkins DSS via Roger Peng
  6. Johns Hopkins DSS via Roger Peng DSS Summary Statistics •

    Total Time Running: 13 months • Avg. Monthly Enrollment: 182,507 • Avg. Monthly SigTrack: 12,771 (7%) • Overall Course Completion Rate: 6% • Signature Track Course Completion Rate: 67% • Capstone Enrollment: 663 (10/2014), 1041 (3/2015)
  7. Johns Hopkins DSS via Roger Peng Scale and Reach 1158

    Science: The End of Statistics? by Larry Wasserman https://normaldeviate.wordpress.com/2013/04/13/data-science-the-end-of-statistics/ Data science: how is it different to statistics? by Hadley Wickham http://bulletin.imstat.org/2014/09/data-science-how-is-it-different-to-statistics%E2%80%89/ Data Science, Big Data and Statistics — can we all live together? by Terry Speed http://www.chalmers.se/en/areas-of-advance/ict/calendar/Pages/Terry-Speed.aspx
  9. … as I have watched mathematical statistics evolve, I have

    had cause to wonder and to doubt.... I have come to feel that my central interest is in data analysis… Tukey, 1962
  10. The statistics profession faces a choice: - traditional topics –

    data analysis supported by mathematical statistics - a broader viewpoint – based on an inclusive concept of learning from data The latter course presents severe challenges as well as exciting opportunities. The former risks seeing statistics become increasingly marginal. Chambers, 1993
  11. Greater Data Science - Data Exploration and Preparation - Data

    Representation and Transformation - Computing with Data - Data Modeling - Data Visualization and Presentation - Science about Data Science Donoho, 2015 Full recognition of the scope of GDS would require … major shifts in teaching.
  12. pick zero or one: data science is ‘just’ statistics data

    wrangling is not statistics placeholder for a whole slew of things

    ednesday, October 30, 13 Slides from Hadley Wickham's talk in the Simply Statistics Unconference http://t.co/D931Og8mq3 We can’t focus just on this!
  14. How STAT 545 projects go sideways: An Incomplete List inability

    to … scrape data off the web … get data from an API … parse JSON or XML utter defeat by date times text encoding fiascos ineptitude with regular expressions R scripts that consume infinite time and RAM software installation gong shows
  15. permission requirement to invest time in setting up tools and

    to develop proficiency “simple” descriptive stats exploration through visualization tame data from the wild, including the web + APIs readiness for open science and automation create an R package alpha to omega: raw data to a web page or app STAT 545 now
  16. R markdown Git(Hub) Data wrangling, cleaning, munging Visualization (R chops,

    in general) 8 weeks 4 weeks Automation & pipelines R packages Shiny Web APIs and scraping STAT 545 = 1 semester, 3 contact hours/wk
  17. MOOCs and weekend bootcamps are great BUT I have concerns

    about all this stuff living outside the regular academic envelope Do we signal it isn’t that important? What are career implications for those who embrace? Are we in denial about the need to make room for this in our regular programs?
  18. To a very great degree, daily work by other people

    sounds easy -- certainly easier that what we have to do. Gretchen Rubin
  19. Don’t study artifact, study nature. Consider: Behind every wildly successful

    tool there’s probably a very powerful abstraction. Don’t over-study mathematical complexity while under-solving real world complexity.
